Members

filled

bitflag of flags using the bits of enum nl80211_sta_info to indicate the relevant values in this struct for them

connected_time

time(in secs) since a station is last connected

inactive_time

time since last station activity (tx/rx) in milliseconds

rx_bytes

bytes (size of MPDUs) received from this station

tx_bytes

bytes (size of MPDUs) transmitted to this station

llid

mesh local link id

plid

mesh peer link id

plink_state

mesh peer link state

signal

The signal strength, type depends on the wiphy's signal_type. For CFG80211_SIGNAL_TYPE_MBM, value is expressed in _dBm_.

signal_avg

Average signal strength, type depends on the wiphy's signal_type. For CFG80211_SIGNAL_TYPE_MBM, value is expressed in _dBm_.

chains

bitmask for filled values in chain_signal, chain_signal_avg

chain_signal[IEEE80211_MAX_CHAINS]

per-chain signal strength of last received packet in dBm

chain_signal_avg[IEEE80211_MAX_CHAINS]

per-chain signal strength average in dBm

txrate

current unicast bitrate from this station

rxrate

current unicast bitrate to this station

rx_packets

packets (MSDUs & MMPDUs) received from this station

tx_packets

packets (MSDUs & MMPDUs) transmitted to this station

tx_retries

cumulative retry counts (MPDUs)

tx_failed

number of failed transmissions (MPDUs) (retries exceeded, no ACK)

rx_dropped_misc

Dropped for un-specified reason.

bss_param

current BSS parameters

sta_flags

station flags mask & values

generation

generation number for nl80211 dumps. This number should increase every time the list of stations changes, i.e. when a station is added or removed, so that userspace can tell whether it got a consistent snapshot.

assoc_req_ies

IEs from (Re)Association Request. This is used only when in AP mode with drivers that do not use user space MLME/SME implementation. The information is provided for the cfg80211_new_sta calls to notify user space of the IEs.

assoc_req_ies_len

Length of assoc_req_ies buffer in octets.

beacon_loss_count

Number of times beacon loss event has triggered.

t_offset

Time offset of the station relative to this host.

local_pm

local mesh STA power save mode

peer_pm

peer mesh STA power save mode

nonpeer_pm

non-peer mesh STA power save mode

expected_throughput

expected throughput in kbps (including 802.11 headers) towards this station.

rx_beacon

number of beacons received from this peer

rx_duration

aggregate PPDU duration(usecs) for all the frames from a peer

rx_beacon_signal_avg

signal strength average (in dBm) for beacons received from this peer

pertid[IEEE80211_NUM_TIDS + 1]

per-TID statistics, see struct cfg80211_tid_stats, using the last (IEEE80211_NUM_TIDS) index for MSDUs not encapsulated in QoS-MPDUs.

Description

Station information filled by driver for get_station and dump_station.
